Hybrid Gis-Bim Approach for the Torino Digital-Twin: The Implementation of a Floor-Level 3d City Geodatabase

Abstract

Abstract. The research tries to present a preliminary work into geo-spatial management of public administration assets thanks to interoperability of BIM-GIS models, related to urban scale scenarios. The strategy proposed tries to deepen the management, conversion and integration of databases related to public assets and particularly schools building, and related them into city-related geo-databases. The methodology, based on the real scenario of Torino Municipality and their needs addressed in recent studies in collaboration with FULL – Future Urban Legacy Lab from Politecnico di Torino, take advantage from the availability of two test dataset at different scale, with different potential and bottlenecks. The idea of developing a 3D digital twin of Torino actually stop long before the 3D city modelling only, but rather we have to deal with the integration and harmonization of existing databases. These data collections are often coming from different updating and based on non-homogeneous languages and data models. The data are often in table format and managed by different offices and as many management systems. Moreover, recently public administrations as the one of Torino, have increase availability of BIM models, especially for public assets, which need to be known, archived, and localized in a geographic dimension in order to benefit from the real strategic potential of a spatial-enabled facility management platform as Digital Twin. Combining the use of parametric modeler software (Revit) and visual programming language (Dynamo), the proposed methodology tries to elaborate rules on a set of shared language parameters (characterizing the buildings as attributes in both datasets: ID; address; construction; floors; rooms dimensions, use, floor; height; glass surfaces). This is tested as conversion workflow between the Municipality DB and the BIM model. This solution firstly allows the interaction and query between models, and then it proposes open issues once the enriched BIM model is imported into the geographical dimension of the Torino 3D city model Digital Twin (ArcGIS Pro platform), according to LOD standards, and enriched with semantic components from municipality DB.

Urban Echoes: Exploring the Dynamic Realities of Cities through Digital Twins

“…The experiences in Turin that can be recalled so far concern the production studies of 3D models oriented toward BIM-GIS integration, the exploration of data modeling platforms at the urban scale, and their adaptability and compliance in terms of interoperability at the architectural scale [47,48]. Since 2022, the Municipality of Turin has been collaborating with the SDG11lab (https://www.dist.polito.it/en/the_department/laboratory/sdg11lab, accessed on 9 March 2024) of the Politecnico di Torino to create the digital twin of the entire city; the creation of the 3D model based on specific high-resolution aerial images is only the starting point for obtaining new geospatial data, making existing data interoperable and providing useful tools for managing urban complexity.…”

3d Webgis Applications for Digital Humanities Studies: The Turin 1911 Project

“…The WGS84UTM32N system -EPSG 32632 -is preferred to the Web Mercator -EPSG 3857since the first one is more suitable to minimize distortions in a local area, such as the Valentino Park. Values for origin and rotation are set in BIM software, and then the model is saved and loaded in GIS software, using the integration method from BIM to GIS and using the procedure of georeferencing in Revit and importing in ArcGIS exploited in Sammartano et al, 2021.…”
